I used this to check to see if anything was being forwarded for one of my users
Get-InboxRule -Mailbox <mailboxname>
This brought back something like this:

MailboxOwnerId : XXXXX/Users/XXXXXXX
Description : Take the following actions:
redirect the message to 'XXXXX@yahoo.com'
and stop processing more rules on this message

When I run the command you mentioned on the same name, I get nothing back.
So, I'm confused.
I need to find users who are creating rules in Outlook or OWA that allow them to forward mail. Then I need to delete those rules and stop them from creating any further rules.
Can you please help?
Thanks.
